The candidates were expected to connect the circuit as shown, measure and record the ammeter readings, plot the graphs of currents against each other, determine the slopes of the graphs and do some comparison.
The expected answers were:

(j) Comparison: The current divides in inverse proportion to the values of R1
and R3.

As reported by the Chief Examiner, the readings obtained by many of the candidates that answered this question showed that they did not know how to adjust meter settings to correspond to indicated values of measured quantities.
